Mikasa Maxima Sorrento pattern cup and saucer: 21,200 ppm Lead (90 is unsafe for kids) + 167 pm Cadmium.

When tested with an XRF instrument (for repeated 30 second tests on each component) the Mikasa cup and saucer pictured here had the following readings:

Zinc (Zn): 32,500 +/- 800 ppm
Copper (Cu): 79+/- 38 ppm
Iron (Fe): 461 +/- 123 ppm
Vanadium (V): 1,046 +/- 225 ppm
Titanium (Ti): 2,820 +/- 414 ppm
Zirconium (Zr): 1,565 +/- 50 ppm

Floral area – blue and red:

Lead (Pb): 18,900 +/- 500 ppm
Cadmium (Cd): 167 +/- 17 ppm
Barium (Ba): 476 +/- 78 ppm
Tin (Sn): 199 +/- 26 ppm
Zinc (Zn): 23,800 +/- 700 ppm
Zirconium (Zr): 1,735 +/- 69 ppm
Platinum (Pt): 357 +/- 155 ppm
Cobalt (Co): 1,599 +/- 162 ppm

Floral area – yellow:

Lead (Pb): 21,200 +/- 600 ppm

Antimony (Sb): 77 +/- 27 ppm

Tin (Sn): 264 +/- 27 ppm

Zinc (Zn): 24,900 +/- 700 ppm

Iron (Fe): 453 +/- 143 ppm

Zirconium (Zr): 1,782 +/- 69 ppm

Platinum (Pt): 315 +/- 152 ppm

How much Lead is too much Lead?

The amount of Lead that is considered unsafe and illegal in a modern / newly manufactured item made and sold for use by children today is anything 90 ppm Lead or higher in the paint / glaze or coating and anything 100 ppm Lead or higher in the substrate. Dishes are not covered by this regulatory standard as they are not considered to be “an item intended for use by children” (however it is my professional opinion that they should be because children also use dishes!)
